摘要
通过实际工程案例,介绍了复杂地层条件下浅埋暗挖隧道密贴下穿大跨度市政隧道的设计方案及施工措施,数值模拟了隧道开挖对既有市政隧道的位移影响,并与实测数据进行了比较分析,为类似项目提供参考。
Based on the project, this paper introduces the design and implementation of a shallow-buried tunnel, close paste under across existing municipal highway tunnel. The project is characterized with complex stratum conditions, the numerical simulation analysis method is used to study the impact of approaching construction on the stability of municipal highway tunnel, and the reliability of the numerical calculation results is verified by combining with the field monitoring data. The conclusions provide some reference for similar projects.
